50 points! Plz help Why can eukaryotes be considered "combination" organisms?

Some of their genes and cellular characteristics were derived from archaea, and others from bacteria.
They eventually developed flagella.
They eventually developed cellulose plates.
Their diversity outnumbers prokaryotes by over one million species.

In pea plants, yellow seed color (y) is dominant and green seed color (y) is recessive. based on the punnett squares, what are the chances that the offspring in the second generation will have green seeds? first generation y y y yy yy y yy yy second generation y y y yy yy y yy yy there is a % chance that the offspring will have green seeds.
